The check engine light is a feature in modern vehicles that tells the driver when something is wrong with the engine or any other major component of the vehicle. When the light comes on, most people feel a sense of dread because it could be an indication of a costly repair. However, not all check engine lights are created equal, and knowing the difference between a steady and flashing light can be the difference between a non-emergency and a potentially life-threatening situation.
What Does a Check Engine Light Mean?
A check engine light is part of the onboard diagnostics system built into modern vehicles. This system can detect any issues with the engine or other components and store codes indicating the problem. The check engine light comes on when the system detects a problem by illuminating a warning light on the dashboard. Typically, the light is orange or yellow, but some older vehicles may have a red light to indicate a more severe issue.
When the check engine light comes on, it does not necessarily mean that there is something seriously wrong with the vehicle. However, it is not something that should be ignored. Even a minor issue that is left unaddressed can lead to more significant problems down the road.
